Anyone know how this is done with the new Mercedes keys like below.
On my old a class (w177), if you double pressed the lock button it would deactivate the keyless entry. This doesn't work anymore so wondering if it's a different combo now

Hmmm I don't think they changed it I still see people doing so and it still works, did you happen to check the user manual if it tells you anything, alternatively you could also use a faraday pouch. Sorry if my reply wasn't as helpful as you hoped.

Thanks as always forum member superswiss, so I stand corrected and that there were changes, I could had sworn that some W206 people got it to work by double pressing the lock button but as you confirmed for us that I remembered it incorrectly. Interesting how MB changed it to this, maybe people were complaining that keyless go was not working not knowing they press the lock button twice in quick succession in previous models? I learned something today.

Yeah, it's possible that the double-click was too easy to trigger accidently and perhaps could even happen with the key in your pocket and doing a "butt-lock" so to speak. Also since the last generation of key fobs were introduced with the W213 and then added to other models such as the FL W205, the fobs now also have a motion sensor in them and deactivate automatically after 2 minutes of not sensing any motion, so the manual deactivation has become less important. This change was done in response to the relay attacks that have become popular in recent years, so now if you leave the fob sitting around in the house, you no longer have to worry about thieves stealing the car from your driveway by relaying the key fob signal, and at the same time it preserves the battery.

I didn't no, and I've seen this... Its the "keyless go" part which threw me. I was more interested in just keyless entry which previously was different to disabling keyless go. It seems a tad overcomplicated getting out the car and doing the above rather than the previous double lock press.
Edit to say - even previous keys had the built in motion sensor which disabled the key after a period of no motion.

How was deactivating keyless go and entry different before? In my FL C205 C63 they are both disabled with the double-click and there's the motion sensor as mentioned. The PFL W205 had the removable button to disabled keyless go and no motion sensor. Agreed, it's a tad complicated now, but as I said, there's less of a need, IMO. I pretty much never need to manually deactivate it.

I should probably add that I'm London based sometimes they clone when you click the lock button from nearby or after you're walking from the car. The double lock was just a nice and easy safety addition

Well, if they clone the key then deactivating it doesn't help. It only deactivates the fob. If they managed to clone it while you are deactivating it, they'll get into your car. Doesn't seem cloning is really still a thing as the fobs these days use changing codes. Each time the car is locked/unlocked the code changes. That's why the relay attacks are much more popular. Somebody actually has to follow you while the second person stands near your car. In that case deactivating your fob is a nice safety addition as the fob will sense motion while you are walking and not deactivate itself.

Actually for 2022 C300 it's still doble click on the lock button. Don't know from what manual screenshot was taken in the post below. At least it works this way for my 2022 C300. May be 2023 is different.

This means that 2022 and 2023 are differet in this regard.
It appears that way. Maybe the new bulkier key fob design proved to be more prone to accidentally double clicking the lock button with the fob in one's pocket. The previous key fob design was slimmer and less bulky. The new fobs are kind of a step backwards, IMO.

Interesting, so that means I was right yet wrong...
